The men were charged with possession of an explosive or incendiary device, conspiracy to commit terrorism and providing material support to terrorism — with bail set at $1.5 million each — in what is described as a potential plot to attack President Obama's re-election headquarters and Chicago Mayor Rahm Emmanuel's house.

The three men were among nine people detained on Wednesday night in an apartment raid in Chicago's Bridgeport neighborhood. Police confiscated what they say is equipment to create Molotov cocktails, which the protesters say is equipment for making beer, according to the Chicago Tribune.
